DRUM-HEAD STRAINER.

SECIFICATION forming part of Letters Patent No. 350,870, dated October l2, 1886.

Applicaiion tiled cvcrnhcr 7, 1885.

To @ZZ whom it may concern.'

Bo it known that l, EDWIN J. CUBLEY, a

My invention relates to improvements in drum-strainers, in which hooks attached to the drumhoops are operated by the rotation of a metal rod having a screvvthread; and the objects of my improvements are, first, to reduce the proj ecting thickness of such druinstraincrs to its nlininninr; second, to prevent the bending of the central rod under strain by bringing1 the line of strain as near to that of the rod as possible, third, to provide a simple, eiiective, and convenient method of rotating the rod, and, fourth, to simplify the construction and eheapen the cost of such druln-strainers. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure l is a side viev.r of the drum-strainer having the hooks cut away to show the interior construction. Fig. 2 is a view of the key used to rotate the rod within the hooks.

lar prqiection, I3, at one end. The nictalhoolis C and D are drilled entirely through and have in part of their length a feniale screwthread mating that upon the rod. The lccy G, Fig. 2, is a piece ol' rod having` a flat or angular notch, H, to iit the projection B on the rod A, and having also a suitable handle-piece, K K. rlhe hooks, shaped as in the drawings, bear closely around the edge and upon the side of the drum-hoop, so as to endure a severe strain inthe line ofthe connect-ingrod. As the rod is turned by the key,thc strain is increased or diminished at will.

I ani aware that priorto niy invention straining devices having a central connecting-rod with right and left hand screw-threads have been made. I therefore do not claini snch a combination, broadly; but

` I do claim and desire Letters Patent forq A drum-straining device consisting` ot' the rod A, having the projection B, in combination with the hooks C and D, conntcrbored lo cover such projection, and the key G, having` the angular notch II, all substantially as set forth.
